APPARATUS FOR MANUFACTURING CHARCOAL.

SPECIFICATION formingpart of Letters Patent No. 701,145, dated May 27,1902.

Application filed May 25, 1901.

T0 all who/1t 'it 'n1/(ty concern:

Beit known that I, CHARLES J. T. BURCEY, of Syracuse, in the county ofOnondaga land State of New York, have invented a certain new and usefulApparatus for Manufacturing Charcoal, of which the following is aspecification. Y Y ,Y

My invention has for its object the production of an apparatus formanufacturing charcoal which is particularly simple in construction andefiicient in operation; and it consists in the combination,construction, and arrangement of the component parts of an apparatus forthe desired purpose, as hereinafter fully described, and pointed out inthe claims.

In describing this invention reference is had to the accompanyingdrawings, forming part of this specification, in which like lettersindicate corresponding parts inall the views.

Figures l and 2 are respectively top plan and side elevations, partly insection, of a preferable embodiment of my apparatus for manufacturingcharcoal. Fig. 3 is a sectional view taken on line 3 3, Fig. 1.

The illustrated preferable embodiment of my apparatus comprises,essentially, one or more chambers A for receiving the Wood to betreated, combustion-chambers B, one or more conduits C for conductingthe liberated gases and vapors from the chambers A,'a condenser D,communicating with the conduits C, a conduit E for receiving theproducts discharged from the condenser, and a gas-conduit F,communicating with the condenser and having branches discharging,respectively, into the receiving-chambers A and the combustion-chambersB.

The chambers A are provided with heatconducting passages a al a2 a3,presently described, areof any desirable form, size, and construction,and any suitable number thereof may be employed, although I have hereillustrated but two. Said chambers are each provided with openings andclosures a4 therefor, unnecessary to describe, which permit the entranceof the wood and the removal of the charcoal, and are also provided withopenings a5 in their side walls and closures therefor, also unnecessaryto describe, which permit the entrance of a tool, as a bar, in or-`Serial No. 61,901. (No model.)

der that the attendant may determine as to Whether or not the wood issufficiently charred.

The interiors of the chambers A, which receive the Wood to be charred,are substantially air-tight and do not communicate with the passages,presently described, for conducting the products of combustion from thecombustion-chambers B.

The heatconducting passages a extend vertically in substantially thecentral portions of the bases of the chambers A and are formed withclosed upper ends, and the heatconducting passages a' are arranged inthe bases of the chambers A, extend substantially radially andhorizontally from the passages u, in proximity to portions of theinteriors 0f the chambers A, substantially' equidistant from each other,and are formed with radial inner ends a, communicating with the passagesc, laterally-extending intermediate portions a7, and radial outer endsas, being thus of substantially zigzag form. The passages a2 are alsoarranged at the bases of the chambers A, are substantially ring-shapedin form, and communicate with the outer ends of the passages a', and thepassages as communicate with the passages a2 and the outer ends of thepassages a', extend upwardly therefrom within the interiors of thechambers A, and are formed with outwardly-deflected upper ends a, whichproject through the side walls of the receiving-chambers A and are'provided with exits and closures therefor, unnecessary to describeherein. The parts of the passages a a a2 a3 arranged in prox;- imity tothe different contiguous portions of the interiors of thereceiving-chambers A are provided with inclosing Walls for preventingthe escape of the products of combustion from said passages into theinteriors of the receiving-chambers.

The combustion-chambers B are of anyde.- sirableform, size, andconstruction and communicate with the main heat-conducting pas- IOO andvapors driven off from the wood within the corresponding chamber A, andis provided with suitable means, as a valve c, for preventing thepassage vtherethrough of said gases and vapors. The condenser D is alsoof any desirable form, size, and construction, being generally providedwith an upper chamber d, connected to the conduits C, substantiallyupright passages d', depending from the chamber d, and a lower chambercl2, communicating with the lower ends of the passages d'. Saidcondenser D is also provided with a substantially upright passage orchamber d3 for receiving a cooling fluid, as running water, and with aninlet and an outlet d d5, communicating, respectively, with the lowerand upperportions of said passage or chamber d3.

As clearly seen in the drawings, the conduit 'E for receiving theproducts accumulating in the condenser is arranged in suitable proximityto said condenser and is provided with an inlet c, into which saidproducts are discharged by an outlet-pipe e', exten ding outwardly fromthe chamber cl2 of the condenser and provided with a branch exit-passagee2,

v having a suitable valve.

f3,`having a valve.

In the operation vof my invention the chambers .A are alternately filledwith the wood to betreated, the charring in one chamber bein'g completedat the time the treatment of the woodin the other-chamber is commenced.The'products of combustion generated in the chambers B escape throughthe passages a c a2 ato the 'atmosphere without contacting with the woodand in transit impart sufcient heat' to the wood to liberate thevolatile elements therefrom and transform the wood to charcoal. A Duringthe charring of the wood the operator'makes frequent tests by insertinglbars through the openings in the side walls Vof the chambers A andstriking the wood orcharcoal, and in case he ascertains that thecharring is not taking place uniformly he varies the treatment of thewood by closingthe exits of a number of the heat-conducting passages aScorresponding to the wood treated to the greatest extent, whereupon allof the heat escaping through the passages. c-

is conducted through the remaining heat-conducting passages as. Thegases and vapors driven off from thevwood pass through the conduits Cand the condenser D, and certain ofsaid volatile 'products becomecondensed and flow through the outlet-pipe e' to the conduit E, by whichthey are conducted to any desired locality for recovery. Whenfirst'treating thewood, a large amount of steam is expelled therefrom,forming water in the condenser, and this water is usually permitted toescape through the branch exit-passage e2 for preventing undue dilutionof the products discharged into the conduit E. Certain of the gaseousproducts discharged into the condenser do not become liquid, but pass asa gas into the conduit F, whence they may be discharged into thechambers B and A, the gas being discharged into the chambers B formaintaining combustion therein and being discharged into the chambers Aonly after the wood is sufficiently charred and for the purpose ofcooling the charcoal and preventing any combustion thereof. Theenlargement or chamber f2 of the conduit F collects any vapor passingthrough the conduit F and permits of the escape thereof, and the gauzepartition of said chamber prevents the passage of the fire from thechambers B to the gases in the condenser.

The construction and operation of my apparatus will now be readilyunderstood upon reference to the foregoing description and theaccompanying drawings, Vand it will be particularly noted that more orless change may be made in the component parts thereof without departingfrom the spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
